Canning at about 5,510 ft in Butte

Butte at about 5,510 ft
Butte, the Richest Hill on Earth, is the highest of Montana's featured towns at about 5,510 ft, canning from the upper stretch of the 3,001–6,000 ft band. Uptown's steep streets climb toward the Continental Divide, but they'd need nearly 500 more feet to reach the next row.
Adjustments come in bands, not curves. The whole 3,001–6,000 ft band gets the same 10 added minutes and the same 13 lb dial setting, so the difference between your kitchen and about 5,510 ft almost never matters. Live near the top of the band and unsure which side you're on? Use the higher band — a little extra processing costs texture; too little costs safety.
As for the number itself: Butte's elevation was checked against the USGS elevation service, starting from the NOAA weather-station inventory (BUTTE BERT MOONEY AP). Elevation shifts block to block in any town, but the bands are wide on purpose — a station a few miles out almost never changes the row.
Not your kitchen? The altitude lookup turns any ZIP or town into a card like this one. Recipe already in hand? The processing time adjuster takes your recipe's minutes and applies Butte's band for you.
Frequently asked questions
How many minutes do I add to a water-bath recipe in Butte?
Add 10. Butte sits at about 5,510 ft, in the 3,001–6,000 ft band, so whatever process time your tested recipe gives for the lowest band, add 10 minutes to it and hold a full boil for the whole time.
What pressure do I set in Butte?
13 lb on a dial gauge, 15 lb on a weighted gauge. Weighted gauges come in fixed steps, which is why the weighted number sits higher than the dial's — both reach the tested temperature inside the canner at Butte's elevation.
My kitchen isn't at exactly about 5,510 ft — do my numbers change?
Almost certainly not. The whole 3,001–6,000 ft band shares one answer, so block-to-block differences around Butte are already priced in. The only case worth a thought is a home near the band's edge — then use the higher band's numbers, which err on the safe side.
Do pressure-canning times change with altitude too?
No — this is the part canners like. A pressure canner restores the tested temperature by raising pressure, so the minutes stay exactly as the recipe states them. In Butte that means the right pounds — 13 on the dial, 15 weighted — and the printed time, unchanged.
